Eiji chooses Hyōbu to represent the ESP unit in the duel with the navy fighter, but the words of his father that he should refrain from using his powers keep haunting him as he trains for the upcoming match. In the day of the duel, it is revealed that the pilot representing the navy is the same one involved in the incident. Hyōbu finds himself in a pinch against the enemy until he finally manages to overcomes his fear and wins the duel by a direct paint shot in the cockpit. Soon after, a US submarine is seen pursuing three dolphins who contact Hyōbu and the others through ESP asking for their help, just before one of the dolphins is killed by a torpedo. With the navy fighter's help, the ESP unit manage to save the other two and shake off the pursuers. However, the dolphins warn Hyōbu about an ominous fate awaiting him and his companions. Years later, just after the atomic bombing of Hiroshima, Eiji informs Hyōbu that Japan is about to surrender and most of the ESP unit is dead. However, by using the brain of Ihachigo, one of the dolphins, Eiji has a precognition that Hyōbu will bring destructon to the world in the future and decides to dispose of him. Eiji fires thrice on him, one bullet to the head, but Hyōbu manages to survive and strikes back, apparently killing him, and leaves swearing vengeance on the normals who betrayed him and his friends.
